I want to reshape the original vectors?

hi every one

If I have the following vectors

x= [1 2 -6 9 -7 8 -8 -5 2 4 -6 4 -4 -5 -7 6 10 2 3 7 -8 9 -8 -5 4 -6]

Xp=x(x>0)

Xn=x(x<0)

Xn=abs(Xn) %%%%%%%%%%%%%%%%%%%%%%%%%

after separated the signal is transmitted

fr=[length(Xp), Xp, Xn]

then in the recevier Rx

rp=fr(2:fr(1)+1); % positive Rx

rn=fr(2 + fr(1):end); %negativ Rx

then I want to reshape the vector as original vectors

can any one help me

thank u very much
